分布式电站光伏汇流箱布置优化策略

Optimization strategy for locating of combiner box for distributed photovoltaic power station

针对曼哈顿算法在解决汇流箱选址问题时的局限性,提出了综合线损和财务净现值经济性比选方法,兼顾考虑电缆用量及成本、直流线损、20年发电量和发电收益等因素,对具体案例进行了计算,将不同方案的结果进行了比较分析。结果表明,该方法可有效降低电缆用量、减少线损,提高系统效率,达到发电收益的最大化,弥补了单一算法的不足,可为汇流箱的优化布置提供参考。

In view of the limitation of Manhattan algorithm in solving the problem of locating the combiner box,a comprehensive method for cable loss and net present value is proposed. Taking into account the factors such as cable consumption,cost,DC cable loss,power generation in 20 years and revenue,specific cases are calculated and the the results of different schemes are compared and analyzed. The results show that this method can effectively reduce the cable consumption,cut DC cable loss,improve system efficiency,maximize the generation benefits and make up for the shortcomings of the single algorithm. It can provide a reference for the optimal layout of the combiner box.
